Key result
PMADL-8 demonstrates excellent reliability for assessing functional limitations in CHF patients.
Why the study?
Current self-reported measures for functional limitations in CHF patients lack specificity for disease-related symptoms and do not guide therapy based on outcome data.
Population
50 CHF patients for reliability and validity testing; 37 elderly CHF patients and 37 age- and sex-matched controls for discriminative validity
Comparison
CHF patients vs age- and sex-matched general population controls
Design
Cross-sectional study with expert panel input and pilot testing

Supports PMADL-8 for functional assessment in CHF; leaves open its prognostic utility and responsiveness in prospective studies.
Cross-Sectional (n=124)
The PMADL-8 is a reliable and valid self-reported questionnaire for assessing disease-specific functional limitations in patients with congestive heart failure.
Shimizu et al. (2009) conducted a cross-sectional in Congestive heart failure (n=124). Performance Measure for Activities of Daily Living-8 (PMADL-8) vs. Age- and sex-matched controls was evaluated on Internal consistency, reliability, and validity. The PMADL-8 questionnaire demonstrated excellent internal consistency (Cronbach's alpha 0.94) and test-retest reliability (ICC 0.96) for assessing functional limitations in CHF patients.
